Be it known that LJosnP A. hhnro- (JELLO, a citizen of the United. States, residingat Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Air Valve and Nozzle, of which the following is a specification.

Myinvention relates to valves and nozzles used to feed air from air laterals to the c1r- "culatio'n pipes ofice cans for raw Water ice-making systems.

fTlie purpose'of my invention to pro,

- vide a simple an linexpensive combined i ficationand in the claims, I Ihaveflpreferred to illustrate -my inven valve. and nozzle, provided with convenient and reliable means for opening the valve to blow out the impurities.' A further purpose is 'to' provide a valve with an opening of size'to pass through it continuously a proper quantity of air ancl with a valve extension, preferably through the valve nozzle, Whereby the valve may be unseated for blow-oil purposes.

A further purpose is to hold the valve in place by a wire through which the valve is unseated for removal of aocurm'ilated 1 mpurities.

' i-Further purposes will appear in the speci-.

tion by but one general form, selecting a I forinwhich is simple, practical and inexpens lve and winch at the same time Well h Figure 'valvefand wlrel emoved from the nozzle illustrates the prinoip'lesof my invention.

The inlet here 18 is larger thaguthe bore 19 of the tm'ininal'l, so that, comparatively the former a. countorhore and. thuspro sides a shoulder Qflwhich acts as a valve seat about the adjoining bore 19. Thisseat is preferably.Tconical but in any event, operativcly conforms to the end 21 of a plug valve 22. v

The plug valve is smaller than the bore 'ofat-h'e inlet, not only to permit movement Within it but also to provide for passage of air between the side Walls of theplug valve and the hero resmtfihfily, giving .a plentiful supply of air for nit/Wing out,

The obstruction may thus be blown out by the air blast. For this purpose I supply a wire 24attached to the able way and most desirably projects beyond the end 25 ofthe nozzle. The wire may, however, merely be accessible from the front of the nozzle. The projection should be short .in order that it ma not readil inter ere with the to give side access.

The Wire permits more free movement of the valve within reasonable limits if it be bent inilie within it without side binding or with any desired amount ofside binding, where as a wire without spring will have its shape given to it by engagement with the side ment protects the valve I ameter small enough of the deslgner, without cure and walls of the passage and will bind more within the passage. In either event the engagement of the wire with the Walls of a bent passage caused by withdrawal movefrom careless or acshould be of a dinot to interfere with free movement of air through the passage.

In operation the nozzle is introduced into the pipe of the appropriate can, the air is turned o'n and by reason of the leakage air is fed through to the canlin the predetercidental loss. ;The wire mined amount."

' When'therel'is any a preciable reduction or stoppage of air feed the nozzle is withdrawn from the pipe seated by pressingagainst the wire 24 either directly, if it projects,v as preferred, or by any implement if it be desired to have the 'wlreterminate short of the end of the nozzle. his causes an immediate greatly increased flow of within. the pipe. The pressure of the air at the back keeps the valve seated and restricts the air flow to the leakage intended.
